To all whom it may concern..- 7

Be it known that I, RUFUS HERRIOK DORN, of the city of Los Augeles, inthe county of Los Angeles, in the State of California, have inventedcertain new and useful Improvements in Miter-Boxes, of which thefollowing is a full, clear, and exact description or specification,reference being had to the annexed. sheets of drawings and to theletters marked thereon.

The improvements in miter-boxes which Upon the annexed sheets ofdrawings, Figure 1 is a plan of the lower part of the circularmiter-box, showing such of my improvements applied thereto as arevisible in a plan of the circular table thereof. Fig. 2 is an invertedplan of the under parts of my improved miter-box. Fig. 3 is a frontelevation of my improved miter-box. Fig. 4 is a rear elevation of theright-hand and part of the lefthand back or movable leaf of my improvedcircular miter-box, showing the ring attachments. Fig. 5 is a plan ofthe attachment of the leaf shown at Fig. 4 to the central pivot at theunder side of the table of my improved miter-box. Fig. 6 is a transversesection of my improved miter-box, taken in the plane of the saw upon theline so to, Fig. 1, by which molding or other lumber is cut in myimproved miter box and which plane corresponds to that occupied by thesection of the saw shown at Fig. 3. Fig. 7 is an edge elevation of aremovable supporting inclined stop used in connection with the othermovable stops of myimproved miter-box, and this removable stop is forthe purpose of giving support to the rear face of half-moldings whensuch half-moldings are placed in the miterbox to be cut at an angle fromthe rear face thereof. Fig. 8 is a plan of the removable stop shown inelevation at Fig. 7. Fig. 9 is a front elevation of an ordinarycrosscut-saw adapted under my present improvements for being used 'in myimproved miter-box. Fig. 10 is a plan of the handle end of thiscrosscut-saw so adapted. Fig. 11 is a front elevation of the front slidein which said crosscutsaw so adapted operates. Fig. 12 is an elevationof the rear slide of my improved miterbox, wherein said crosscut-saw soadapted is operated. Fig. 13 is a transverse section of the outward endof the crosscut-saw and the parts applied thereto for adapting saidcrosscut-saw to be operated in my improved miterbox and which section istaken upon the line y y, Fig. 9.

Upon Figs. 1, 3, and 6 the circular table of my improvedmiter-boxismarked A A, and

the two angularly-movable leaves of the said miter-box are marked B B,respectively. At the center of the under part of the circular table A Aof my improved miter-box there is formed a strong pivot C,'Fig. 6, andupon,

this pivot are carried each of the two rings D and D, to an arm E,projecting from each side, of which and shown more particularly at Figs.4 and 5 each leaf B and B is respectively carried or attached thereto inthe man'- ner now to be described. Each arm E of each ring D and D is soshaped, as shown at Fig. 4 more especially, that the upper ends thereofpass up into the'circular or segmental openings F, formed in thecircular table A A, as shown more particularly at Figs. 1, 2, and uponthis upraised part of each arm E each of the backs B and B isrespectively carried by being attached thereto by means of screws a a,which pass through the vertical bracket, (marked G in Figs. 1, 3, 4, and5,) so that the vertical brackets G each pass up through an opening inthe flange H at the rear of each back or leaf B or B, which rests closedown upon the fiat portion of the arm E, while the upright portion ofthe arm E constitutes an ample vertical support for maintaining eachback or leaf B or B in a rigid vertical position, such as is requiredfor the movable backs or leaves of a miter-box, and with the View ofsimplifying generally the construction of these parts of myimprovedmiter-box I. mount the rings D and D (more especially shown at Fig. 6)upon one and the same pivot 0, through which a central screw or bolt Iis passed, as shown at Fig. 6, which by means of the nut J and; washerK, placed on thelower end thereof, maintains not only the two rings Dand D and the leaves or backs B and B in operative relationship witheach other and with the miter-box generally, as is well understood, butwhich central pivotal attachment also carries the circular ring-stand L,upon which the entire miter-box rests, and is capable of being turnedaround upon into any angular position required and to be fastened orscrewed in said angular position in the manner hereinafter described.The circular stand L is constructed with arms L, as more particularlyshown at Figs. 2 and 6, and at or near the periphery of its under sidethere are placed pointed feet M, by which the entire miter-box issupported upon the bench or other supporting-surface whereon it is usedfor cutting miters, as is well understood.

In order to fasten the miter-box in any angular position whereat it isor may have been turned upon its vertical axis or pivot O, ashereinbefore described, a vertical set-screw N is passed through atapped hole in the rear part of the circular table A A, as shown atFigs. 1 and 6, and this set-screw on being tightened by turning it insuch direction that its lower end presses upon the upper part of thecircular stand L L causes a part of the edge of that circular stand L Lto be pressed against the inturned lip of a lug or bracket 0, formedupon the under side of the circular table A A, and in this manner thecircular table A A and the circular stand L L become so tightly pressedtogether at this point of both that so long as the set-screw N is thuscaused to press downward upon the circular stand L L the miter-boxbecomes securely held in any angular position required, while byreleasing the pressure of the set-screw N- that is to say, by unscrewingit at the pressure contact with the circular stand L L- is released andthe entire miter-box then becomes free to be turned around upon thepivot G into any other angular position required.

Afurther part of my presentimprovements consists of a modified form orconstruction of the lever P by which each leaf B or B is retained in thenotches Q at the under side of the table of the miter-box for holdingthe leaves or backs B or B in any required angular position, and thislever P is constructed with a rearward-projecting arm P, as shown moreparticularly in the rear elevation of the leaf or back B at Fig. 4. Thislever P is pivoted upon a pin P' and operated upon at the outer end ofthe arm P by means of a spring R, fastened to the upper part of theopening S'in the under part of the leaf or back, by which it passes overthe stop T when the angular stop U is not fastened thereon. In

Figs. 1, 3, 6, 7, and 8 of the drawings the action of the springRis topress upward against the under part of the arm 'P, and thereby tomaintain the lever P in such position that the retaining-catch P,forming the lower end thereof, is held in any one of the notches .Q Q Qin the under part of the circular table A A, while by applying the handto the upper part of either lever P and by pressing either lever P untilthe upper part thereof comes into contact with the projecting lug V(shown at Fig. 4) either of the retainingcatches P is moved out of anyof the notches Q Q Q and in which position of the retaining-catch eitherof the leaves or backs B or B is free to be rotated to any other anglerequired. By releasing the hand from either of the levers P P theretaining-catch P enters into and engages with any notch Q and againretains either back or leaf B or B in the requisite operative angularposition. The supplementary stop U, which is used only for givingsupport to the rear of half-moldings when such half-moldings are beingcut in my improved miter-box, consists simply of a fiat piece of metalU, as shown in several of the figures, but more especially on a largerscale in Figs. 7 and 8, and which supplementary stop is constructed witha slot W at the lower flat end thereof, so that this part of thesupplementary stop may be passed under the lower part of the thumb andfinger screw T, and is thereby securely or firmly fastened to the stopin any required position to give support to the back or rear of ahalfmolding, as shown more particularly at Fig. 6.

It is to be understood that the saw used in this improved miter-box isan ordinary tenonsaw, such as is shown at Y in Fig. 3 and in dottedlines indicating its position, in Fig. 6, but which is not shown in theother figures of the drawings, because such saw, being a feature ordetail common to all miterboxes, constitutes no part or my presentinvention.

As shown by Figs. 9 to 13, the crosscut-saw (marked X) is of the kindcommonly used by carpenters, joiners, and others and is operated with anordinary wooden handle, as shown more especially at Figs. 9 and 10. Toadapt such a saw for being used in the slides of my improved miter-boxafter the manner wherein the tenon-saw (marked Y Y) is shown at Fig. 3of the annexed drawings, 1 apply or adapt to an ordinary crosscut-saw Xthe back or frame, (marked Z.) This back or frameis held onto the saw Xin the following manner: The back or frame is constructed at its outerend with a narrow opening 11 b, the width of which opening I) b issufficient to admit of the outer end of the saw passing thereinto, andthe outer end of the sawX has formed in it the parallel notch 0, (showndotted in Fig. 9,) of a width equal to the diameter of the transversepin d, which is situated in the opening I) b, as shown more particularlyin the transverse section, Fig. 13. By means of this pin d and the notchc in the saw the outer ends of the frame or back Z become united or heldtogether, and at the rearward or handle end of the saw the back Z andthe saw X are held together by means of the spring 6, which is fastenedto IIO oily vapors, as well as increasing and maintaining a uniformdraft.
